Angle 1 and angle 2 are supplementary

1 = 124°
2 = (2x + 4)°

what is the value of x?

supplementary means equal to 180.

180 - 124 = 56.

56 = (2x+4)

2x = 52

x = 26

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
